Butternut Squash Lasagna

Butternut Squash Lasagna 6.000
Nov 4, 2009

Make Ahead: You can make the squash/sauce up to 3 days in advance; cover and refrigerate. Then assemble and bake.


Servings: 6 - 12

Yield: Makes 6 main dish or 12 side-dish servings

Ingredients
  • 3 pounds butternut squash (about 9 1/2 cups flesh), peeled, seeded and cut into 1/2-inch dice
  • 3 tablespoons vegetable oil
  • Kosher salt
  • 4 cups low-fat milk
  • 2 large sprigs rosemary
  • 1 tablespoon minced garlic
  • 4 tablespoons (1/2 stick) unsalted butter
  • 4 tablespoons flour
  • 9 no-boil lasagna sheets (7 by 3 1/2 inches each; use fresh ones if you can find them)
  • 1 1/3 cups (about 5 ounces) freshly grated Parmesan cheese
  • 1 cup heavy cream

Directions

Preheat the oven to 450 degrees. Line 2 large rimmed baking sheets with aluminum foil.

Toss the diced squash with the oil in a large bowl until well coated. Spread in a single layer on the baking sheets. Roast for 10 minutes, then sprinkle with salt to taste. Stir the squash and roast for 10 to 15 minutes, or until tender and beginning to turn golden brown.

While the squash is roasting, heat the milk in a saucepan over medium-low heat. Add the rosemary and cook for 10 minutes. Strain through a fine-mesh strainer into a large pitcher or measuring cup.

Melt the butter with the garlic in a large saucepan over medium-low heat. Whisk in the flour and cook, stirring constantly, for 3 minutes, to form a roux. Remove the pan from the heat and add the warm milk mixture in a steady stream, stirring until smooth. Return the pan to medium-low or low heat and cook for about 10 minutes, until the sauce has thickened. Add the squash and salt and pepper to taste, stirring to combine. (At this point, the mixture can be refrigerated in a bowl with plastic wrap directly on the surface.)

When ready to bake, reduce the oven temperature to 375 degrees. Lightly grease a 9-by-13-inch baking dish.

Pour 1 cup of the squash-sauce mixture in the bottom of the dish (it will not cover completely). Cover with 3 lasagna sheets, making sure they are not touching each other. Spread half of the remaining sauce over the pasta and sprinkle with 1/2 cup of the Parmesan. Repeat with another layer of pasta, then the remaining sauce, then another 1/2 cup of Parmesan, and finally a layer of pasta on top.

Combine the cream and 1/2 teaspoon of salt in the bowl of an electric mixer. Beat on low to start then on high for several minutes until stiff peaks form. Spread evenly over the top pasta layer, making sure to cover the pasta completely. Sprinkle with the remaining Parmesan. Cover tightly with easy-release/no stick aluminum foil and bake in the middle of the oven for 30 minutes. Remove the foil, then bake for 10 minutes, or until the top is bubbling and golden. Let the lasagna stand 5 minutes before serving.
